Allen, how do we proceed? Do you want to send a new version of yours, or should I go on with a v2 for this one? Regards, Angelo
Hi Angelo, I can send a new version with this series. Thanks for help convert schema.

Hi Krzysztof, Thanks for the reminder. There is also a series [1] for mediatek watchdog. I would have to wait until [2] merged before sending a series for "Convert mtk-wdt" in order to prevent a conflict, but [2] has not yet been merged.
